A student is on the roof of a 100m building with 2 cannonballs. Each of the scenarios below are independent (i. e. your answer to part 1 is not applicable to part b). a. If the student drops one cannonball, and exactly 1.0s later drops the other cannonball from the same height. What is the time interval between the first cannonball striking the ground and the second cannonball striking the ground?
b. If student drops one cannonball, and after it has fallen exactly 1.0m drops the other cannonball from the same initial height. What is the distance between the cannonballs when the first cannonball strikes the ground?
c. The student throws one cannonball directly upward at 5.0 m/s and simultaneously throws the other cannonball directly downward at 5.0 m/s. (This requires great dexterity, but the student has been practicing this maneuver for several months.) What is the difference in speed between the cannonballs when each ball strikes the ground and what is the difference in their times to landing?
